Description

We have studied the energy resolution of a prototype gas tracking calorimeter in a test beam at Fermilab as part of the detector development program for the MINOS long baseline neutrino oscillation experiment. The calorimeter consisted of 25 layers of 1.5 inch thick steel plates interleaved with planes of aluminum proportional tubes. The tube cells are square, with 0.9 cm edges and open tops. Cathode strips were used for read out transverse to the wire cells. The tubes operated with a nonflammable gas mixture of 88% CO{sub 2}, 9.5% isobutane and 2.5% argon which gave an operating range of >500 ... continued below

Description

We have studied the energy resolution of a prototype gas tracking calorimeter in a test beam at Fermilab as part of the detector development program for the MINOS long baseline neutrino oscillation experiment. The calorimeter consisted of 25 layers of 1.5 inch thick steel plates interleaved with planes of aluminum proportional tubes. The tube cells are square, with 0.9 cm edges and open tops. Cathode strips were used for read out transverse to the wire cells. The tubes operated with a nonflammable gas mixture of 88% CO{sub 2}, 9.5% isobutane and 2.5% argon which gave an operating range of >500 V (limited by the electronics). We read out the wire signals on the tubes and in some configurations the cathode stripe as well. We studied positrons, pions and muons over a momentum range of 2.5-30 GeV/c and achieved energy resolutions of about 40%/{radical}E for EM and 71%/{radical}E for hadronic showers.
